JS Date Validation Example
Cut and Paste Code
Cut 'n' paste code for the above Example
Function isDate is used to verify if the given value is a valid date in the format (mm/dd/yyyy) : This function first specifies the non-digit character which is allowed in the date ("/" is used here). You can also specify the year range between which the date is valid. These changeable values are declared in the lines (found in the beginning of the code) :
// Declaring valid date character, minimum
year and maximum year
var dtCh= "/";
Now the date string is seperated into the month, day and year integers. They are each validated seperately and combined together.
